To uaZZ whom it may concern,.-

Be it known that 1,-WALTER G. MORRISON, a citizen of the United States, and a resident of Stonington, in the county ofNew London and State of Connecticut, have inventeda new and useful QuIlingMachine, of which the following is a specification.

My invention relates to quilling-machines, and has for its object to provide certain new and useful improvements in the structure, arrangement, and mode ofl operation of the quill-holder, the bearing or bolster therefor, and the means for driving the guide-carrier support.

A practical embodiment of my invention is represented in the accompanying drawings, in which- Figure l is an enlarged side elevation of the quill-spindle, the bearing, the friction driving-pulley, the guide-carrier support, the parts arranged to operate in conjunction therewith, and the support therefor. Fig. 2 is a top plan view of .the same. Fig. 3 is a view similar to Fig. l, taken at right angles thereto; and Fig. 4 is a vertical central section through the bearing, the friction driving-pulley, and the guide-carrier support, the vertical quil1-holderbeing represented in side elevation in its normal position therein.

I have represented'in. the accompanying drawings only so much of quilling-machine frame as will enable a clear understanding of the operation of the several parts to whichV this present invention is directed.

B designates one of the side rails of the machine to which a cup-shaped bearing or bolster K- is permanently secured. This bolster K has a `downwardly-extended hollow central lug k, which has-a screw-threaded engagement with the rail B, the lower end of thesaid lug k 'projecting below the bottom of the said rail and being there provided with a lock-nut 7o for rigidly holding the bearing in its position. This bearing or bolster K has a hub k2 and an annular rim k3 concentric therewith, so as to form an annular oil-cup around the hub. The hub k2 preferably extends a short distance abovethe top of the rim k3. i

The spindle is denoted by G'andis disposed vertically and extended upwardly through the interior of the said cup-shaped bearingl or bolster K. A vertically-reciprocating move- `ment is imparted to the spindle G by the usual.

mechanism, (Not shown herein.)

A friction driving-pulley L is lmounted to rotate within the bearing K, which pulley L is in the present instance provided withja hub Z, which is mounted-to rotate on the hub 7a2 of the bearing and a peripheral rim 6o Z. The bottom of `the hub Z rests uponthe bottom of the cup-bearing K, and the rim Z' is exterior to the -rim k3 of the bearing and is spaced a slight distance therefrom. The

upper portion of the friction driving-pul- ,Y

tween the hubs of the pulley and bearing into the space within the flange Z4 will be permitted to escape downwardly through the duct or ducts Z5 back into the oil-cup within the bearing.

The guidecarrier support is denoted by M, 8o

which support is provided on its bottom with an annular ange m, having its inner wall Haring, so as to snugly it the tapered top of the friction driving-pulley L when the guidecarrier support rests in engagement therewith,whereby therotary movement of the pulley is communicated to the guide-carrier support. The guide-carrier supportis still further provided with a downwardly-extended ltubular portion m', which engages the inner 9o wall of the hub k2 of the bearing with an easy sliding fit, the connection between the tubular portion m and the hub k2 being such that the rotary movement4 of the guide-carrier support will not be unduly impeded by the frictional engagement between the said tubular portion and hub. The'bottom-of'the guidecarrier su pport M is provided with an annular shoulder m2 around the base `,of the downwardly-extended tubular portion m', the said .100.v

shoulder serving to prevent the free escape of the oil from thespace within theyflange ZH A lining-tube 7a4 is fixed to the base of the bearing K and extends upwardly with an easy sliding fit within the tubular portion m of the guide-carrier support M, which liningtube extends upwardly to a point above lthe top of the friction driving-pulley L. The guide-carrier support is provided with two uprising posts or rods m3 m4, upon which the thread-guide carrier N is fitted to slide,which guide-carrier may be readily removed from and inserted onto the said posts. The guidecarrier is mounted upon the uprising posts of the support M in such a manner that the guide-carrier may be readily raised short distances'at a time, but will be prevented from an unintentional downward movement. The means which I have shown in the accompanying drawings for accomplishing this result comprise a rack m5 along the bar m3 and a spring-actuated pawl n, carried by a downwardly-extended tubular extension n of the guide-carrier N. This pawl n may be provided with a suitable tailpiece n2, which may be readily grasped for raising the pawl out of engagement with the teeth upon the bar m3 when it is desired to slide the guide-carrier downwardly thereon.

To prevent the cramping of` the guide-carrier N, I preferably provide a downwardlyextended tubular portion n3, arranged to engage thc uprising post m4.

The thread-guide (denoted by O) may be of any well-known and approved construction, its stem o being adjustably secured to the guide-carrier N, in the present instance by means of aset-screw o', which serves to clamp the shank o within a socket in the carrier.

A loose lifting-ring P is mounted in antifriction-bearings in the guide-carrier in position to surround the top of the quill-holder and engage the top of the quill as it is being wound, whereby the continuous winding of the quill will gradually force the guide-carrier upwardly until the winding of the quill is completed.

In the present instance a casing 1J is securedA to the under side of the guide-carrier, and within the casin g are located the loose lifting-ring P and a row of antifriction-balls p. By this arrangement whenever the quill engages the loose lifting-ring P the ring will be held stationary as far as rotary movement is concerned, while the guide-carrier continues its movement around the quill.

The mechanism which I employ for Stopping the rotation of the guide-carrier support, and thus stopping the winding of the quill when the quill is completed, is constructed and arranged as follows: A supporting-rod Q is supported a short distance below the side rail B in a bracket q, which bracket is secured by a suitable bolt g4 to the under side of the said side rail B. A weighted stop-lever R is mounted to rock upon the rod Q adjacent to the spindle G, the outwardly-extended arm of the lever R being the weighted arm, the weight in the present instance being utilized as an operating-handle r. The vertical rocking movementJ of the lever R is limited by a bifurcated arm S, having its branches s S eX- tended into positions below and above the inner arm of the said lever. This bifurcated arm S is secured to a downwardly-extended arm q of the supporting-bracket q in such a manner that the said arm S maybe adjusted vertically. In the present instance this is accomplished by providing the downwardlyextended arm q' of the bracket q with an elongated slot q2, extended upwardly from its lower end and providing a clamping-bolt s2, arranged to engage the bifurcated arm S and the downwardly-extended arm q. This bifurcated arm S is preferably made double, so that it may serve for limiting lthe swinging movements of two adjacent stop-levers. A vertically -sliding pin T extends upwardly through the bearing or bolster K, the said pin passing vertically through the hub .7a2 and the downwardly-extended portion 7a of the said bearing, the pin being so arranged that when its lower end is engaged by the inner arm of the stop-lever R and raised its upper end will engage the annular shoulder m2 upon the guide-carrier support M, and thus raise the guide-carrier support away from its frictional contact with the driving-pulley L. In the present instance I have shown the inner arm of the stop-lever R as being provided with a laterally-extended lug r', upon which lug the pin T rests at all times by gravity. When the inner arm of the lever R is held depressed and the weighted arm raised, the pin T will engage the shoulder m2 upon the guide-carrier support. By means of a screw-threaded engagement of the bearing with the side rail and the clamping-nut la the bearing may be adjusted in a rotary manner until the pin 'F is brought into the required position with relation to the stop-lever.

A vertically-disposed rock-bar U for locking and releasing the stop-lever R is mounted in upper and lower bearings fu 'U in a support V, carried by the bracket q. This support V has an adjustment toward and away from the side rail by means of an elongated slot n2 in its base rU3 and a clamping-bolt Q3, which engages the base fvg, and the bracket q. The rocking bar U is provided with a laterallyextended lower arm u, which is preferably a portion of the bar itself, which arm extends :into position to engage the upper edge of the stop-lever R. When the rocking bar U is in its normal position7 its lower arm u will rest upon a step r2 in the upper edge of the lever R, the step being so arranged that the lever will be held with its inner arm depressed and its outer weighted arm raised. When the rock-bar U is rocked, so as to swing its lower arm u forward, the arm will be raised from the step r2, and because of the cut-away portion of the upper edge of the inner arm of the stop-lever R the inner arm will be caused to rise, because of the downward movement of the outer arm by gravity. To cause the rock- IOO IIO

bar U lo return to its normal position upon the step r2 when the weighted arm of the stop-lever Ris. raised, I provide a torsionspring u', one end of which spring is attached to the upper bearing fu of the bar U and the other end to a sleeve or collar u2, clamped to the said bar U. This sleeve or collar u2 may be adjusted rotatively for adjusting the tension of the spring u', and it may also be adjusted vertically for adjusting the height of the bar U when the arm uis not resting upon the step r2 of the stop-lever. This sleeve or collar u2 is loosely embraced by two short branches o5 r4, projecting laterally from the support V. This support Vis preferably arranged so as to also support the next adjacent rock-bar. The rock-bar U is further provided with a vertically and rotatably adjustable upper arm r1.3, which arm is adjusted into a position to be engaged and rocked by a tripping-arm '11.4, depending from the guidecarrier N, when the carrier has been raised until the winding of the quill has been completed. The rock-bar U is also provided with a suitable thumb-piece M4 at its top for use in operating the bar by hand when it is desired to stop the winding of the quill.

It will be seen from the above description that thevguide-oarrier support will be raised from its engagement with the friction driving-pulley the inst-ant that the winding of the quill is completed. Furthermore, it will be seen that the operator may at any time also operate the stop-lever for raising the guidecarrier support from the friction-pulley. It will also be seen that the several parts are made thoroughly adjustable with respect to each other, so as to obtain the most efcient results.

It is evident that changes might be resorted to in the form and arrangement of the several parts without departing from the spirit and scope of my invention. Hence I do not wish to limit myself strictly to the structure herein set forth; but

l. In a qui-lling-machine, the combination with a quill-holder, of a stationary cup-shaped bearing or bolster surrounding the quillholder, a friction driving-pulley mounted in the bearing, a guide-carrier support concentric with the driving-pulley and arranged to be driven thereby and means for raising the drive-carrier support from its engagement with the driving-pulley.
